Abstract： 目的 认识良性转移性平滑肌瘤(BML)的CT表现.方法 回顾性分析经病理证实的4例BML患者的CT表现,其中肺BML 2例,腹膜播散性平滑肌瘤(LPD)1例,另1例为既有肺BML又有LPD.均为曾有子宫肌瘤切除史的女性,平均年龄45岁.结果 3例肺BML表现为肺内多发性随机分布的直径0.2～2.0 cm圆形结节,边界光滑清楚,密度均匀无钙化,无肺门纵隔淋巴结肿大及胸水.增强后扫描病变无强化.2例LPD表现为下腔静脉、腹主动脉、髂总动脉邻近处的直径4～5 cm多发性肿块,边缘清楚,密度均匀无钙化,无淋巴结肿大及腹水.1例正电子发射计算机体层摄影(PET)CT肿块未见核素示踪剂明显浓聚.另1例CT增强后肿块有较强的强化.结论 在有子宫肌瘤切除史的女性中,见到CT表现为肺内和(或)腹内出现多发性、边缘光滑清楚、密度均匀的结节和(或)肿块时要考虑到BML可能.
